15,422 tests were conducted on over 3600 samples in our lab which is
certified for bacteria and certain chemical analyses. These samples were
drawn from raw water at Floods Pond in Otis, during the treatment
process at our ozone plant, and from dozens of locations through the
distribution system and for other area utilities.
 The
District's lab uses a methodology for testing total coliforms called
Colilert Quanti-tray. This EPA-approved method provides a better means
of identifying coliform bacteria. Not only are total coliform results
available in 24 hours, E. coli can also simultaneously be detected. The
District collects and tests about 60 finished water samples per month
for total coliforms and E. coli.
We
completed another round of lead and copper samples during 2004; results
were below Environmental Protection Agency action levels. Another
round of lead and copper testing is scheduled for the summer of 2007.
The
most likely source of lead is from your home's plumbing such as copper
pipes with lead solder or faucet fixtures containing lead. The lead then
leaches into standing water in the plumbing. A simple preventative
measure is to flush each cold water faucet in the home for a minute or
two when water stands for more than a few hours. |
